使用Interface Builder在屏幕外创建UIButton

Question

I want to create a big UIScrollView , its contentView should contain more than 30 UIButton . Positions of these UIButton are not rectiligne and cannot be create 'programmaticaly' so I've placed all these UIButton on a UIView manually. I zoom/dezoom and scroll all over my UIScrollView fine BUT here is my problem :
UIButton created offscreen is not accessible, I mean I can't click them (only UIButton created in the CGRect(0.f, 0.f, 320.f, 480.f) can be click.
Any suggestion ?

Answer 1

Create a view, put a scrollView inside that view, and place your buttons on the scrollView. While adding buttons and moving them around, be certain that they're always inside the scrollView by looking at the object hierarchy in interface builder.

You can slide the scrollView around as you place things, no need to zoom. As long as your buttons are children of your scrollView it should work fine.
